[sane-devel] Hello, and HP C3180 drivers

[Robert Charlesworth]

Thanks Alan & Johannes, I didn't know about HPLIP, and didn't realise that
it is included with my Ubuntu distro!
Scanning seems to work fine, both with the Simple Scan frontend and x-sane
(not installed by default).
Seems that's the end of my driver writing project then ;-)
Never mind, I have an old Primax Colorado scanner kicking around somewhere,
so maybe I'll have a play with that.....
